Specification of Letters Patent.

Application filed August 27, 1908, Serial No. 450,537. Renewed March 16, 1911. Serial No. 614,954.

To all whom Ql t'may concern:

l 3e it known that I, JAMES A. GRAY, a citizen of the United States, residing at San Francisco, in the county of San Fran-- cisco and State of California, have invented new and useful Improvements in Can- Heading Machines, of which. the following 13 a specification. My present invention relates to improvements in the manufacture of sheet metal cans and more particularly to means Whereby the can-heads or can-tops and can-bottoms are seamed to the can-bodies.

t is my object to produce a machine of simple construction, of rapid and positive operation, and which can be manufactured -at low cost, whereby the can-heads are seto produce true and hygienic cans.

All these objects are accomplished by a machine, an embodiment of which is shown in the accompanying drawings, which form a part of this specification, and wherein:

Figure 1, is a front elevation of the entire machine. Fig. 2, isan end elevation of the same. Fig. 3, is a plan view of the same. Fig. ,4, is a series of diagrams showing the successive stagesin the process of seaming together the can-heads and the can-bodies. Figs. 5, G, 7 and 8 are broken detailed views of sections of the various plungers which perform the successive stages in the seaming.

table or platform 3. J ournaled in the up- "per ends of the supports is the shaft 4, on

which are the cranks 5, and the cams 6 and 7. Also on the shaft 4 is the drive pulley S and the bevel gear 9. The bevel gear 9 is in mesh with the bevel gear 11 on the shaft 12, which is suitably journaled and supported on the support 2. On the lower end of the shaft 12 is the crank 13 and the sector l4. Near the outer. end of the crank 13 is a'roller provided to engage in the slots 10 of the wheel 15 which is mounted on the shaft 16 that is also suitably journaled and supported on the support 2. This crank 13 in its revolutions will give intermittent motion to the wheel 15 and the shaft 16. The sector 14, in its revolutions with the crank 13' and the shaft 12, :will, in its movement, engage in the concave depressions in the periphery of the wheell5, and so lock the wheel 15 against movement while the crank 13 is in that part of the arc of its motion in disengagement with the slots 10. On the shaft 16' is the sprocket wheel 17 operating in the same plane as the surface of the table 3. Suitably journaled and supported from the support 1 is an idler sprocket wheel 18 revolving in the same plane as the sprocket wheel 17, and on these sprocket wheels 17 and 18 is operated the feed chain 19, which is provided with projections or fingers 21, at equal and suitable distances-apart so that the selected feed of the can-bodies 20 to the selected parts of the machine where the various stages of the seaming operation are performed will be positive.

The beam 22 has a vertical movement in the guides 23, on the supportsl and 2, and motion is given to this beam by means of the cranks 5 and the adjustable ,links 24.. On the lower side of the beam 22 are the plungers- 25., 26, 27 and 28, which are here inafter more particularly described.

In openings in the surface of the table 3 and directly below the plungers 27 and 28 are vertically movable disks 29 and 31,

which normally have their upper surfaces in the same plane as the surface of the table.

raised above the plane of the surface of the table and loweredagain to normal positions at the desiredtime, in the operation of the machine, by means of the levers 32 and 33, the links Bl and 35, and the cams 6 and 7.

On the surface of the table 3 are parallel guides 36 and 37 that are placed beneath the plungers 25, 26, 27 and 28 and so provided that the cans pass between them, guiding the cans to positions beneath the plungers in there progress through the machine. The rear guide 37, as have shown it, is so adapted that the feed chain passes between it and the can-bodies'in a. channel provided along the wall of the guide. These guides extend from a suitable point on the, feeding side of the table before the plunger is reached, as the can-bodies go ,into the machine, to a point on the discharge side of the table after the can has received its final operation by the plunger 28 in the seaming process. These guides also serve as stops.

' inthe operation of the'plungers 25, 26, 27

and 28, the operation of which will hereinafter be more fully explained.

In the 4 drawings I have shown four plungers, each of which performs a distinct operation in the successive stages of forming. the seam of the can-head with the canbody I In Fig, 4, I. have shown the various folds of the sheet metal in each of the successive stages. 'At A is shown a section of a can-body as. it would be flared by the plunger 25. A sectional detail of this plunger.is shown in .Fig. 6. At B (Fig. 4) is showna section of the prepared can-head. AtC (Fig. 4)"is showna section of the canhead in place on a section of the flared canbody. At D (Fig. 4) is shown a section of the can-headand the can-body in which the outer hooked rim of the can-head is turned against the outer flared section of the canbody, as performed by the operation of the.

plunger 26. A detailed'section of plunger 264s shown in Fig. 5. At E (Fig. 4) is shown in section the next stage of the seaming process which is performed'by plunger 27', whereby the-hooked rim of the can-head and the flared portion of the can-body, which'have, by the preceding stage been folded together, are now turned downward toward the can-body, thus forming an acute angle in relation to the plane of the can-.

body. A detailed section of plunger 27 is shown in .Fig. 7. At F (Fig. 4) is shown in section the final stage of the seaming process as performed by plunger 28, a detailed section of which is shown in Fig. 8.' In

this stage the folds of the can-head and the can-body, that have by the preceding proc- 5 esses been folded so as to form any acute angle with the plane of the can-body, are now folded tightly together and pressed against the side of the can-body.

I provide a means for feeding the canheads to posit-ions on the can-bodies at the proper stage of the-operation of the machine, as 'shqwn by the feed chute 38, which is placed between the plungers 25'and 26. The can heads 30 are fed into this chute with their innerv surfaces downward, and they.

.two diameters.

ried and driven by any suitable means. At

the lower end of the chute is an opening 69 directly over the position the can-bodies 2Q assume in the step they take through the machine when they receive the can-heads 30.

The can-heads, when they reach this opening, are held in position directly over the opening by the fingers 71 which press against the edges of the can-heads by means of the springs 72. The can-body, by the intermittent movement of the feed chain, assumes a position underthe opening in the chute. Then the plunger73, onthe beam 22, descends, carrying thef can-head from the fingers through the opening and forcing it into position onthe can-body.

In Figs. 9, l0 and 11,1, show in detail the'construction and operation of the plungers. These plungers are annular cup-shaped members each having an outer member 39, v

which is suitably and rigidly attached to the beam 22, by the shank 41. On the inner surface of the annular member 39 is an annular angular groove 42. The inner edge of the rim of the member 39 is beveled at an angle-43, said angle43 coinciding with the angle of the annular groove 42. Within the member 39, and bearing against its inner surface are the four quadrant pieces 44, 45, 46 and 47, as shown in Fig. 9. These pieces are provided with projections on their outer surfaces which fit into, and coincide with,

.the angle 42 and the angle of the beveled.

rim'43 of the member 39. These angular surfaces form cams in the operation of the plunger.

- When the projections of the quadrants are fitted-into the angular groove 42 and the beveled surface on the rim of the member 39 the quadrants are of such. a length that there is space between the ends of them as shown-by the quadrants 44 and 45, in Fig.' 9. hen the quadrants, are forced upward into the cavity of the member 39, the angular projections on the inner surface of the member 39 act as cams on the angular projections on the outer surfaces of the quadrants, thus forcing the quadrants inwardly and the quadrants then assume the positions shown by the..quadrants 46 and 47 in Fig. 9. The quadrants in the two positionsdescribed' form circles of In the illustration, in Fig. 9, I have shown two of the quadrants in the position of the larger diameter, and two in the positionof the smaller diameter, but it will be understood that in the operation of the plunger all four quadrants act together in making the larger and the smaller dia1n eters.

In openings in the upper surface of the member 39 are the pins 48. Thelower ends of these pins are in engagement with the upper edges of the quadrants, and slidably movable on the said quadrants. In Fig. 9 I have shown two of these pins in engagement with each of the quadrants. At the upper ends of the pins are the springs 49, which are held in place and bear against the plate 51 which is suitably secured to the shank 41.

These springs 49 are provided to bear against the pins 48 which in turn bear against the quadrants 44, 45, 46 and 47, and tend to force the said quadrants downward. The inner surfaces of these quadrants are provided, as shown, with annular angular grooves 52, which coincide with and engage an annular angular projection 53, on the piece 54, which is secured within the center of the cavity of the member 39 by the screw 55, or other suitable means. In the plunger 25 I prefer that this member 54 be solid or a single piece, but in plungers 26, 27 and 28 I provide a pad 56 at the lower face of this member 54. The pad 56 is a metal disk. I have shown it in Figs. 10 and 11 supported and reciprocally movable on the tillister screws 57. Between the disk and the member 54 arethe springs'58, which tend to force the disk downward and away from the member 54 until it'is stopped by means of the heads of the fillister screws 57. The plunger 25 is designed to flare th rims of the can-bodies. In this plunger the quadrants are provided with an annular angular groove 59 on their inner surfaces as shown in Fig. 6. This surface forms an angle with the plane of the inner-surface of the quadrants. I have shown this as an obtuse angle, but I do not confinemyself in construction to any precise formof angle. The member 54,'in this plunger 25, is of one piece, and is tapering at its outer and lower surface so that it will readily enter the interior of the can-body, and adjust the canbody in exact position within the plunger. The member 54 is provided with an annular angular projection 61- on its. outer surface, which coincides with the plane of the angle 59 of the annular angular groove of the quadrants. I prefer in construction that the point of this angle, made with the surface of the projection 61 and the plane of the inner surface of the quadrant, be rounded, or so molded as to form a curve, so as to give an easier progress to the edge of the can-body when the member comes into engagement with the can-body. The movement of this plunger is so adapted that when the quadof the can-body that extends above the quad rants outwardly until it is brought into engagement with and stopped by the coinciding angular projection on the inner walls of the quadrants.

The plunger 26 is designed to turn the outer bend or lip of the can-head over the flare of the can-body as. shown at D in Fig. 4. In this plunger the quadrants are also provided with an annular angular groove 62, on their inner surfaces, as shown in Fig. I have shown the plane of this angle forming an obtuse angle with the plane of the inner surface of the quadrants, but I do not confine myself in construction to the precise form ofthis angle. The member 54, in this plunger, is providedwith a pad as described. This'padis designed to adjust the surface of the plunger to any unevenness in the can-bodies and can-heads, and is provided at its lower surface to fit within the circumference of the rim of the can-head.

On the outer surface of the pad, or disk, 56,

edge of the can-head when the can-head edge I i 7 comes into engagement withth'e quadrants. The movement of this plunger-is so adapted that the quadrants engage, or close on, the can-body just belowfi'the now flared portion of the can-bodythat now has a can-head over it. The can-head is so prepared that it has an annular rim or lip that extends downward around the flared portion of the can-body.

The annular angular projection 63, in the pad or disk 56, as the plunger further descends, compresses the rim of the canhead and the flared part of'the can-body together between the projection 63 and the projection 62, causing the rim of the can-head to'he turned under and against the under, or outer, side of the flared part of the can-body.

The plunger 27 is designed to turn the nowfolded portions of the can-head and the can-body to an acute angle with the plane of the can-body, as shown at E, in Fig. 4. In this'plunger the inner surfaces of the quadrants are provided with an 'annulaizangular groove 64,-as shown in Fig. 7. The

. an annular angular grooveand projection plane of the angle, of this angular groove G t, forms an acute angle with the plane of the inner surface of the quadrants. The member 54 in this plunger is. preferably provided with a reciprocally movable disk, or pad, on

its lower surface as hereinbefore described.

On the lower surface of this disk, or pad, is

65, which coincides with the groove and projection 64 in the quadrants. The movement of this plunger is so adapted that the quadrants engage, or close on, the can-body justbelow the now partially seamed portions of the can-body and can-head.- Then as the plunger furtherv descends the annular an-- gular projection 65, on the pad, or disk 56,

of the member 54, comes into contact with those folded portions of the can-head and the can-body, and forces them downward into the groove 64:. This partially seamed portion of the can-body and the can-head is now hooked into the groove 64. To release the canebody from this plunger I provide the vertically movable plate 29, which in its upward motion at this point coincides with the upward motion of the plunger, and

raises the can-body a suflicient distance to clear the partially seamed portions of the can-body and the can-head from the groove 64 before the quadrants begin to assume their position of the larger diameter.

The plunger 28.'is designed to turn the folded portions of the -can-head and canably provided with a reciprocally movable disk or'pad 56 at its lower surface, as hereinbefore described. The lower surface of this disk is provided to fit over and within the -depression of the' upper surface of the can-head, In the plane with the table, and

directly under this plunger, is the vertically movable plate 31, that is operated by means of a cam on the drive shaft, and a link and a lever as before described. This plate, on which the can-body now rests, rises to a required distance carrying the can-body up ward with it. This motion takes place as the plunger begins to descend. The annular groove 66, provided in the quadrants in the plunger, are so adapted that they, in their movement, engage the cansbody in such a manner-that the partially seamed portion of the can-head and the can-body are within the upper part of the groove in the quadrants, or in that part of the groove in the quadrants where the annulargroove has its' largest diameter. As soon as the quadrants engage the can-body, in the movement of the the quadrants is such thatthe diameter of the "circle formed by the groove in the quadrants is greater at the upper part of the groove than at the lower part 'of the groove. Itwill be seen that when the can-head and the can-body is driven downward tlie' seamed portion will be forced into that part of the ring with the smaller diameter, with the result that the partially seamed portion of the can-head and the can-body, which at the beginning of the operation formed an acute angle with the plane of the can-body, will be forced tightly against the side of the can body, thus completing the seaming operation. As another means of performing this last stage in the seaming operationwith my invention, I disconnect the mechanism operating-the plate 31 in the table beneath the plunger, making the table at this, point sta tionary. The movement of the quadrants is 'so timed that 'they assumethe position of their smaller diameter after the member 56, in the cavity of the plunger, has come into engagement with the top surface of the can- 'head. The ,quadrants will then, in their movement, compress the partially seamed portions of the can-head and the can-body,

which now form an acute angle with the plane ofthe can-body, inwardly against the side of the can-body, thus completing the seaming operation. a

In operatmg my invention, the can-bodies are fed to the machine on the left side of the table, one can-body between each of the fingers of the feed chain. The can-bodies are then carried along to the right between the guides'by the regulated intermittent motion of the feed chain. The feed is so provided, by means of the mechanism herein described, that the can-bod'v will be carried to a point directly beneath the first of the plun- 20 gers. At that point the motion of the feed chain is arrested. This plunger, as described, is adapted to flare the upper rim of the can-body. At the moment the feed chain isstopped in its motion the plunger with its cavity over the can-body descends. In its downward movement a portion of the lower surfaces of two of the quadrants in the plunger are brought into contact with the upper surface of the rear guide, or stop, and a portion of-the lowersurface of the other sum the larger diameter, described, and

two quadrants contact with the upper surface of the front guide, or stop. These guides arrest the downward movement of the quadrants, but the cup-shaped member of the plunger still continues in its downward motion. This causes the angular surfaces on the inner surface of this last mentioned member to act on the angular surwill cause the annular member, centrally 10 cated within its cavity, to enter the interior of the canbo'dy, and the annular projection on this member will press against the inside of the rim of the can-body forcing the rim outwardly until it is arrested by the angular surface of the annular groove in the quadrants. The pins which bear against the quadrants through the openings in the upper cap or wall of the plunger are forced upward with the movement of the quadrants when they come into engagement with the guides or stops. These pins in turn com-. press the springs that are inserted between them and the plate'on the shank, as described. At this point the plunger begins to return to its normal. position. As itrises, the annular member within the center of the cavity of the plungei' is lifted away from the flared upper rim of the can-body. Also as the plunger rises, the compressed springs bear down on the pins which in turn tend to force the quadrants downward. As-the motion continues the inner annular angular surfaces in the quadrants are brought into engagement with the outer annular angular surface oft-the member in thei-nterior of the cavity of the plunger. These angular surfaces have a cam motion, which force outwardly the quadrants and cause them to asso release the can-body. As this is done the can-body is moved forward another step in its progress through the machine by the provided intermittent motion of the feed chain. On this second step I provide for placing the can-heads, which have been pre viously prepared, in the required position on and over the now flared can-bodies. This is done by means of the feed chute provided from either the front or the back of the machine as will be found most convenient and a plunger. In the drawings I have shown it at the front of the machine. The next, or

third step, carries the can-body, which now has a can-head in place over it, by the movement of the feed chain, under the next plunger in the line of movement. The quadrants are closed tightly about the can-body by exactly the same movement as in the previous plunger. Then as the plunger descends the outer angular rim or lip of the can-head is turned under and against the flared portion of the can-body. The releasing motion and the return to the normal position of thisplunger and its parts is similar to that of the plunger previously described. As the releasing motion is completed the feed chain again takes motion and the can-body is carried forward under the next succeeding plunger. The quadrants of this plunger are firmly clasped about the can-body. Then the plunger continues to descend the partially formed seam of the can-body and the canhead is turned downward intothe angu lar recess in the quadrants. This seamed portion is now at an acute angle with the plane of the can-body and is hooked into the annular angular groove in the quadrants.

Now as the plunger begins to rise the plate in the, table on which the can-body now rests also rises, carrying the can-body upward with it and lifting the hook-shaped portion of the seam from the recesses in the quadrants before the quadrants begin to assume their position of the larger diameter. The plunger then resumes its normal position in such manner as the plungers already described and the plate in the surface of the table resumes its position in the same plane as the surface of the table. At this point the feed chain again takes up motion and carries the can-body along to the position for the next step in the seaming process beneath the nextand last plunger. As soon as the hea d are forced downward'through the quadrants from the larger diameter of the groove in the quadrants to the smaller diameter thus forcing by compression the folded rim of the can-head with the flared part of the can-body tightly against the side of the canbody. This operation may also be performed by the inward pressure of the quadrants as before deseribed. It will be seen that this movement of can-bodies and canheads through the machine will be continuous and that with every movement ofv the )lungers each and every stage of the seaming operation will be performed.
